Why can't a city of over 1 million people support more than one historic park/museum? Most cities have dozens. The City of Toronto alone runs 10 historic museums, including Fort York (and that doesn't even include places like Black Creek Pioneer Village, which are not city-owned).Heritage Park and Ft Calgary should have been the same development, we don't need 2 separate historical parks ion the city. It's too bad Ft Calgary couldn't have been kept and maintained like Ft Langley in BC, that area really surprised me how vibrant it was.
I see no problem in preserving the birthplace of the city of Calgary as a public space. Having a sleepy historical museum occupying the space as a placeholder is a much better use than bulldozing the entire area for some crass mega-development like a sports stadium or entertainment complex. Decades from now, when development has eaten up all of the empty lots in the area, the Fort Calgary property will likely be turned into a landmark urban park.
